NFT Smart Contract with a Royalty
I'm trying to implement a functionality of giving a royalties to the owner after NFTs are sold on the secondary market. As I understand there is no default method or something to give a royalty, so I often see the following solution: https://github.com/jklepatch/eattheblocks/blob/master/screencast/379-nft-royalties/contracts/NFT.sol As I understand I have to pass a token to the constructor of this contract before deploying it. So the question is: if I want to mint and sell NFTs on the Ethereum Mainnet, which token should I pass inside the contract constructor? I see this guy implemented his own token for this purpose, but honestly I don't understand how is it compatible with ETH https://github.com/jklepatch/eattheblocks/blob/master/screencast/379-nft-royalties/contracts/MockToken.sol

Question - I want to purchase an Instagram account for around £20k. Is there a smart contract I could use to get the password without risk of being scammed ?
You could look into HTLC hashed timelocked contracts, these are used to make bitcoin lightning channels for example. There is an ETH smartcontract here: https://github.com/chatch/hashed-timelock-contract-ethereum (I haven't checked the code but the explanation & links in the readme is good)
